Fig. is a cross sectional view through the type carrying bars. Fig. 3 is a plan 'view of the traveling carriage. Fig. 1 is a vertical sectional view through said carriage. trating the stops on the type carriers. Fig. 0

is a cross sectional view showing said typecarrier stops. Fig. T is adetailed view of a cam for lifting the traveling carriage. Fig. 8 is a detailed view of the bar for restoring the pins in the traveling carriagc.

This invention relates to a new and useful improvement in calculating machines, and particularly to the means for controlling the type carrying racks from the key-board.

This application is a division of an application filed by me January 14th, 1901. Serial No. 190031, and is a companion to an application filed by me April (3th, 1906, Serial No. 310,739, and which application 310,739 is a composite continuation of said I application 180.03

g I shall not, in this application, describe the details of construction and method 'of operation on various parts illustrated in the drawings, and which, while cooperating with the subject-matter of this application, form no part hereof, as the same are fully disclosed in Belgium Patent No. 202,081.

dated August 21st, 1007.

In the accon'ipanying drawings: 1 indicates the keys of the typewritmg n'iechanism.

Fig. is a plan view illus 3 is the-platen for supporting paper to be printed upon, 8 is the space bar, and 14 are the levers of the adding mechanism provided with heads on their forward ends which are appropriately marked with digits according to the value of the keys, there being ten such digit keys. Key levers 14 are pivoted at 15, and each key lever cooperates with a vertical movable rod 16 at its rear end which rods are guided by plates 17.

18 indicates the frame of a traveling carriage, on the sides ofwhich are flanged wheels 19, running upon a trackframe 20 pivoted upon a rod 21. A cross bar 22 is arranged at the. free end of this track frame and provides a mount for a spring drum 22 whereby the carriage is constantly pulled toward tlfe left looking from the front of the machine, or toward the right looking from the rear of the machine, as shown in Fig. 4. Thi' traveling carriage 18 carries a rack 23 meshing with a pinion 24 mounted on the upper end of a vertical shaft which shaft is controlled by an escapement mechanism in the manner disclosed in my Belgium patent aforesaid. wherebyupon depression of any., one of the digit keys, the carriage moves leftwardly a distance of one step. v

30 indicates pins mounted in the carriage in longitudilml series, said pins having notches 37 in their upper edges which notches are designed to lock the pins in their elevated position by engaging a projection 36. The restoring bar 38 is stationarily mounted above the carriage, said bar being provided with laterally inclined faces 38 and downwardly inclined faces 38 (see Fig. 8) so that wl en the carriage is moved toward the right against the action of the spring pins 36, which have been raised, will be returned to their normal position. The pins 36 are arranged in pairs, each pair being coupled together by a U-shaped spring 30", whereby the pins of a pair are held in their raised and lowered positions.

45 indicate type carriers havingtceth on their rear upper edges for engaging and operating sets of adding wheels 07 and 123. I shall not describe the means for throwing these adding wheels into and out of mesh with the racks. nor the carrying mechanism cooperating therewith, as the same forms no part of my present invention, and substantially the same mechanism is disclosed in my Belgium patent aforesaid. The forward ends of the rack carriers carry type 17 with which coiiperate printing hammers 81, but as these are described in my Bel. gium patent, I shall not give the detailed description of the same here. Each type carrier is provided with a slot 77 near its rear end with which coiiperates a lever 76, each lever being connected to a spring 78 in turn connected to an operating bar 75 carried by side frames 69, see Fig. 1. The upper ends of side frames 69 carry plates 68 between which is mounted a rod 6?, the rear end of one of said plates having an overhanging projection 70, whose function will hereinafter be described.

61 are stop pins mounted in. the rear lower edges of the type carriers, said stop ins being held in position by meahs of a housing plate 60 constituting a guiding frame for said pins. These pins are coupled together in pairs by U-shaped springs'in the maimer before described with respect to pins 36. There are ten stop pins 61 carried by the type carrier, and in order to prevent accidental movement their upper edges are notched to engage the plates 60. The num her of rows of pins 36 is the same as the number of type carriers. and the first step of the carriage 18 incident to the operation of one of the digit hevs is toward the left, thus bringing the first row of the pins 36 under the units type carrier, each step leftward moving the first row of the pins 36 under type carriers of higher denomination. When a number has been set up on is keyboard the, pins 61 and 36 are in viertical alinemcnt, so that when the carriage. 18 is raised the key positioned pins will lift the corresponding pins 61. The carriage is raised iu'imediately upon the movement of the operating shaft 35 by means of a cam 62'. see Fig. 7. which engages the lower end of a pawl or lever 6-lpivoted to the rod 22 of the track 20. Lever 64: is held against -forward movement by pin 65, so that the shaft may be utilized by the operator potentially setting up another number the key-board. i i

The pins 61 wh-iclnare raised, serve as stops" for the type carriers which support them, so that the number struck on the heyhoard will be recorded by the operation of the type carriers and'associated mechanism: The. stationary bar 66 is supported over the frames 60 so that the pins 61 whennot raised or set can'pass thereunder, but the pins which are raised by the elevation of the carriage will be arrested by said bar and thereby arrest the type carriers in position to record and. register the required number. All the type carriers are normally held in alincnxent by a cross rod 67, which also serves to restore "them to normal position.

The rod 67 is carried by the plates 68 before referred to, whose forward ends are pivoted to the vertical lever 69 attached to the rock shaft 50, and which are swung forward when said shaft rocked. The overhanging projection *ZO on one of the plates 68 while in its forward position, engages a lug" 71 on a rod 72 just behind the cross bar 66, and when the plate 68 starts rearwardly will push the rod 1'2 downward so as to restore all of the stops 61 which have been raised and which, at the time of depression of the rod 72 are directly under said rod. Rod 72 is carried by links 73 pivoted to the frame, and is normally held elevated by means of a spring 73.

The levers 69 have arms '1 extending forward andcarrying a rod 75. mounted upon the shrft 50 is a number of levers 76, one for each type carrier and bar 58, and said levers extend upward. alongside A la of the'carriers and bars and have lateral projections which operate in, slots 77, 2, so that when any one ofsaid levers is drawn forward the corresponding carriers 45 or bars 58* will be pushed forward. Said levers are independently movable and are each connected with the rod 75 by aspiring 78. so that forward movement of the levers 69 will draw for 'ard such of the levers 7 6 Whose type carriers or bars 58 are to operate. This results in bringing the stops 61 which had been set up, against the bar 66 thereby reg: isterina the number represented'as before described. A projecting piece ?8* is carried by the carriage 18 just to the left of the first row of pins 36 in such position. that when the carriage is raise as described, the foremost stop Gl'on each type carrier, eX- cept on the carriers whose stops are operated by one of the pins 36, will be raised. and therefore all the type carriers to the left of'those used to record the number Will be held. stationary, because the foremost stops are a'gainst the rear side of the bar 66.

When the shaft 35 rocks rearwardly, such Pivotally 1 ture of the:

of the type carriers as have been positioned forwardly, as before described, will berestored by the bar (37 engaging th v rear wall of theslot in said type carriers -irwhich it 5 operates.
